When using certificate-based ISAKMP authentication (RSA signatures), HP-UX IPSec checks that the identity sent by the other node in the Main Mode (MM) negotiation matches information in the other node’s certificate. HP-UX IPSec always sends its local IP address as its ID value and the appropriate IP address type (IPv4 or IPv6) as the ID type as the ISAKMP ID payload in MM exchanges. HP-UX IPSec accepts the following ID types from nodes it communicates with:

—IPv4 address (ID_IPV4_ADDR)

—Fully Qualified Domain Name (ID_FQDN)

—User-Fully Qualified Domain Name (ID_USER_FQDN)

—X.509 Subject Distinguished Name (DN, ID_DER_ASN1_DN)

IPv4 ICMP Messages

Discarding or requiring IPv4 ICMP messages (Internet Control Message Protocol messages, IP protocol value 1) to be encrypted or authenticated may cause connectivity problems. Normal network operation may require IP to exchange ICMP messages between end-to-end hosts and between an end host and an IP gateway (including router devices). IP may need to exchange ICMP packets with gateway nodes even though no user (end-to-end) services are being used to the gateways.

Be careful when configuring the default IPSec policy or IPSec policies that affect entire subnets, because you may inadvertently cause ICMP messages to be discarded. You may also inadvertently require ICMP messages being transmitted or received from a non-IPSec gateway or router to be authenticated or encrypted, which will also cause ICMP packets to be discarded.

IP uses ICMP messages to transmit error and control information, such as in the following situations:

•IP may periodically send ICMP Echo messages to gateways to determine if the gateway is up (“Gateway Probes”). If no response is received, the gateway is marked “Dead” in the IP routing table.

This feature is controlled by the IP kernel parameter ip_ire_gw_probe. By default, this feature is enabled on all HP-UX systems. Refer to the ndd (1M) manpage for information on checking or changing this parameter value.

•IP may use ICMP Echo messages with the “Don’t Fragment” flag and ICMP Destination Unreachable messages with the “Fragmentation Needed” flag to set the Path Maximum Transmission Unit (Path MTU).

This feature is controlled by the IP kernel parameter ip_pmtu_strategy. Refer to the ndd (1M) manpage for information on checking or changing this parameter value.

•IP may send ICMP Redirect messages to redirect traffic to a different gateway.

The transmission of ICMP Redirect messages is controlled by the IP kernel parameter ip_send_redirects. By default, this feature is enabled on all HP-UX systems. Refer to the ndd (1M) manpage for information on checking or changing this parameter value.

•IP may send ICMP Source Quench messages to request the source system to decrease its transmission rate.

UX IPSec Software specifications

HP-UX IPSec Software is an integral component of the HP-UX operating system, providing robust and secure communication capabilities for enterprise environments. As organizations increasingly rely on secure networking solutions, HP-UX IPSec stands out with its comprehensive set of features and technologies designed to safeguard sensitive data.

One of the core characteristics of HP-UX IPSec Software is its implementation of the Internet Protocol Security (IPSec) framework. This technology secures Internet Protocol (IP) communications through authentication and encryption, ensuring the integrity and confidentiality of data transmissions. By leveraging IPSec, HP-UX provides a secure method for connecting remote users and secure sites over untrusted networks, such as the internet.

A notable feature of the HP-UX IPSec Software is its support for both transport and tunnel modes. The transport mode encrypts only the payload of the IP packet, whereas the tunnel mode encapsulates the entire IP packet within a new packet, allowing for secure communications between entire networks. This flexibility enables organizations to tailor their security strategies based on specific use cases and requirements.

HP-UX IPSec also emphasizes interoperability and compliance with industry standards. The software supports various encryption algorithms and authentication methods, including those defined by the Internet Engineering Task Force (IETF). This commitment to open standards ensures that HP-UX can seamlessly integrate with a diverse range of networking infrastructures and security solutions.

In addition to its security features, HP-UX IPSec Software offers administration tools that simplify the configuration and management of IPSec policies. The software includes a user-friendly command-line interface, allowing system administrators to specify security associations and policies efficiently. Moreover, comprehensive logging and monitoring capabilities help organizations keep track of their security posture and detect potential vulnerabilities.

Another essential characteristic of HP-UX IPSec Software is its scalability. Designed to accommodate the needs of both small and large enterprises, it can handle increased loads and adapt to changing security demands without compromising performance.

In conclusion, HP-UX IPSec Software stands as a vital solution for organizations seeking to protect their data transmissions over IP networks. With its core technologies, such as transport and tunnel modes, adherence to industry standards, user-friendly administration tools, and scalability, it provides a formidable layer of security in an increasingly interconnected world. This makes it a preferred choice for enterprises aiming to enhance their network security frameworks.
